Constrained relay node placement in wireless sensor networks: formulation and approximations
—One approach to prolong the lifetime of a wireless sensor network (WSN) is to deploy some relay nodes to communicate with the sensor nodes, other relay nodes, and the base stati...

A framework for processing complex document-centric XML with overlapping structures
The key of overlapping structures or concurrent markup hierarchies in XML encodings of documents is that markup in one hierarchy is not necessarily well-formed with respect to the...
